MODEL 1000L
1200 WATTS CW
2500 WATTS PULSE
10kHz-220 MHz
The Model 1000L is an economical, self-contained, air-cooled broadband amplifier designed for
laboratory applications that require instantaneous bandwidth, high gain and high power output. Housed
in a stylish contemporary enclosure, the Model 1000L is smaller than competitive units with similar
power levels. All operating controls are functionally grouped on the front panel for simplicity of
operation. These include modern, lighted push-button switches for the command functions, POWER,
STANDBY, OPERATE and PULSE, a control for setting the output level of the amplifier, and a meter
for monitoring critical operating voltages and currents. Remote control is provided through a rear panel
mounted connector. Isolated TTL level remote control can be accomplished using our CP2001
interface. Isolated IEEE-488 compatible control can be provided with our CP3000. A highly versatile
unit, the Model 1000L features rugged circuitry and a quick-acting, solid state crowbar circuit to
protect the final amplifier tubes from damage due to internal arcing. An electronic circuit is provided
to enable rapid gating or blanking of the amplifier.
